Just to make sure we're talking about the same thing, I mean these guys:
We have:
Iron Munro: veteran superhero, knows heroing inside and out, but also that he's not all powerful and needs help
Steel: resident tech genius(yeah several others are good with tech, but he is the guy who really specializes in it)
Livewire: long time villain, now trying to be a hero, also it's neat the various ways she can use her powers. A slice of life issue with her finding various things to do to annoy/help her team mates would be hilarious.
Super-Chief: a bit of a newbie to the superhero scene, so he could be written as the team rookie, also a bit of a blank slate as he was such a new character that we didn't even find out what his actual name was.
Supergirl and Superboy: They've been in team books, but I don't remember one with them together.
It sounds like the start for a neat story.
I'd also love to read a story with Lashina and Kal-El jr though.
